Comment:

 This is clearly a video memory problem (i.e. not enough) and hence I'm
 closing as there's nothing else obvious to be done for 0.22.

 r22132 added the ability to reduce the video buffer size to save some
 video memory. This may help but will probably not work if the h264 streams
 have much more than 2 reference frames.

 The other major video memory saver is changing the UI theme to something
 fairly lightweight - all those images need to be stored in video memory at
 some point.

 Disabling any extra GPU options will also help; OpenGL vsync, VDPAU
 deinterlacing, VDPAU filters etc.

 For reference, MythTV will never have the same video memory footprint as
 mplayer. This is primarily down to the GUI but also due to differences in
 video buffering.
